Answer:
frog
Explanation:
frogs live their first part of their lives in water so they need gills but after metamorphosis they live on land so they need lungs.
Answer:
B — to relate the type of box material to the warmth of air within the box
Explanation:
She changed the box material and measured the warmth of the air in the box.
A is wrong. The question does not mention the mass of the box.
C is wrong. The boxes were all the same size.
D is wrong. Each box was exposed for the same length of time.
The first law, also known as Law of Conservation of Energy,Thermal energy<span> is the internal </span>energy<span> of an object due to the kinetic </span>energy states that energy cannot be created or destroyed in an isolated system. | Nuclear energy<span> originates from the splitting of uranium atoms a process called fission. This generates heat to produce steam, which is used by a turbine generator.</span>
then the chemical<span> bonds are broken, | the potential </span>energy<span> is released in the form of kinetic </span>energy<span> or </span>energy<span> of motion and heat or non useable </span>energy. The kinetic energy is used to do work. | <span>Objects have </span>mechanical energy<span> if they are in motion and or if they are at some position relative to a zero potential </span>energy<span>position for </span>example, a brick held at a vertical position above the ground or zero height position. A moving car possesses mechanical energy<span> due to its motion </span>
The second law of thermodynamics states that the entropy of any isolated system always increases.
